You need to open your app. when you have WiFi or data (while at home is recommended) before you get to the property. If you need access before 8:00 am, the lockbox owner will need to change the access hours on the lockbox to accommodate you. If you have a key card, you can update it after 4:00 pm the previous day for an early morning showing. Please be sure to update the card again on the day of showing after you are done at the property so that the proper contact information gets sent to the listing agent.
